FILTERING APPARATUS Filed Feb. 19, 1949 2 Sheets-Sheet 2 INVENTORS. HANS HOGEMAN JOHNNHUMBEJZ PAUL G. B'JTZMAN Patented May 19, 1953 STATES A NT OF I E 2,639,036 m'rramo APPARATUS man, Longmeadow,

of New York Application February 19, 1949, Serial No. 7.404 4 Claims. (01. 210-185) This invention relates to filters and has particular reference to a new and improved oil filtering apparatus.

An object of the invention is to provide a new and improved oil filtering apparatus wherein the filter is in the form of a completely sealed interchangeable cartridge.

Another obj" ct of the invention is to provide a newand improved oil filtering apparatus which is par ticularly adapted for use in filtering oil for (30111131165sion ignition engines.

Another object is to provide a filtering apparatus for oil engines'in which'apparatus the filter cartridge is removable and may be replaced by a completely sealed filtering cartridge.

' Other objects and advant ges of the invention will be apparent fromfthe following description taken" in" connection with the "accompanying drawing and it will be understood that changes may be made in the details of construction and arrangement of parts without departing from the scope of the invention as set forth in the accompanying claims as the preferred form has been shown by way of illustration only.

" Referring to the drawings:

Fig. 1 is a top 'or plan view of a filtering apparatus embodying the invention;

' Fig. 2 is a front view, partly in section, of the apparatus shown in Fig. 1;

Fig. 3 is a fragmentary, exploded view of the filtering element shown in Fig. 2;

Fig. 4' is a top or plan view of the filter cartridge before the cartridge is placed in operative position thefilte'ring apparatus;

Fig. 5 is a fragmentary view taken on line 55 of Fig. 1 looking in the direction of the arrows; and

Fig. 6 is a. sectional view taken on line 66 of Fig. 5 locking in the direction of the arrows.

Referring more particularly to the drawings wherein similar reference characters designate corresponding parts throughout the several views, the device shown embodying the invention comprises a filter element or cartridge assembly the ring clamp 2 and supporting bracket 3 adapted to be secured in position by bolts or screws through the openings 4 to retain the filtering apparatus in position on the engine.

' The'ring clamp 2 is secured to the bracket 3; by means of the bolts 5 which extend through openings in the cover portion 6 of the bracket 3 and a e threaded nto the ri c a p 2- The cover portion 6 is provided with the conduits l and 8 which are secured to the oil inlet lines 9 and I rflfipctively by the threaded connections shown although other forms of couplings may be employed and the conduits 1 and 8 communicate with the filter through the passageways l I and l 2 whereby oil may pass to the filtering element or cartridge and from said element to the oil supply line.

The cover member 6 is provided with the threaded plug I3 and also has the inserts l4 and I5 having the projections 1.6 and I! respectively adapted to automatically open the fuelpassage- .ways in the cover l8 of the filter element or cartridge l as hereinafter described.

The filter cartridge or element l comprises the container I9 of metal or other suitable material and has the threaded plug 20 in the lower side thereof.

Within the hollow container I9 is positioned the spider 2| on which is positioned the cardboard backing 22 over which are positioned the elements 23 of filter paper or other suitable filtering material which are separated by the pressed cardboard spacing elements 24 and 25 as shown.

lhe filtering elements 23 and the spacers 24 and 25 all have a central opening 26 which form the oil chamber 21 when the members are stacked in aligned relation as shown in Fi 2.

The spacing elements 24 have the openings 28 communicating with the central opening" 26 to allow' passage of oil therethrough and the spacer member 25 has similar cut-out portions or openings 29 in the periphery'thereof allowing the entrance of oil therethrough to the'filtering members'23 from the oil inlet conduit ll'.

At the upper end of the filtering element there is positioned a card-board backing snowmen is similar to the backing 22 previously described.

The we e c p is f he filt en 13 is secured to the container [9 by soldering or welding'or other suitable process after'the filter members 23. spacers 24 and 25 and cardboard 2 2 and are positioned within the contain'er l9 as previously described and this cap or cover it is provided with the lancings 3| and'32 as shown in Fig. 4 which extend partly through the mat'erialof said cover or cap'lfiy but yet allow said filtering member or container to becompletely sealed against dirt or dust and remain sealed until the portions within said lancings 3| and 32 are displaced by the projections l6 and M respectively in the inserts l4 and I 5 as previously described.

The container IQ of the filtering element is provided with the integral peripheral flange 33 adapted to be positioned on the upper surface of the ring clamp 2- as shown in Fig. 2 and Fig. 5 to retain the filtering element in operative position 3 and the gasket 34 may be provided for sealing purposes.

In the construction and assembly of the filtering apparatus, the filtering element 1 is formed with the filtering members therein as previously described and with the cap or cover I8 secured thereto and sealed as also previously described.

When it is desired to place the filtering element I in operative position, the ring clamp 2 is removed by unscrewing the bolts 5 and the filtering element is then inserted through the ring clamp 2 and retained in position therewith by means of the flange 33 which is supported on the ring clamp 2. By then threading the bolts 5 into the threaded openings in the periphery of the ring clamp 2, the ring clamp 2 and filtering element I are drawn into close relation with the cover 6 and simultaneously the projections 16 and I! operate to open the inlet and exit openings in the cover l8 by displacing the portions of the cover within the lancings 3| and 32.

In operation oil passes through the supply line 9, conduit II and opening in the cover l8 which is formed by displacing the portion of the cover within the lancing 3| and said oil then flows around the periphery of the cardboard member 30 and through the filtering members 23 and reaches the sump or central accumulator 27 through the cut-outs 28 in the cardboard spacers 24 from which it passes to the supply line H) through the conduit I2 and the opening in the cover or cap l8 formed by displacing the portion of the cap or cover l8 within the lancing 32.

The filtering element is provided with the outlet bushing 35 which serves to support the cover or cap l8 and also prevent the leakage of oil to the outlet conduit l2 except from the central sump 21.

It will be noted that as there are no openings formed in the cap or cover I8 until it is placed in operative relation on the filtering apparatus, that it is impossible for dirt or dust to pass into the filterin chamber as the filtering element is positively sealed until placed in operative position on the filtering apparatus.

From the foregoing it will be seen that we have provided simple and efficient means for obtaining all of the objects and advantages of the invention.

Having described our invention, we claim:
